ACR/EULAR classification criteria for Takayasu arteritis

The American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) classification criteria for Takayasu arteritis is a clinical tool designed to aid in the diagnosis and classification of Takayasu arteritis. The target patient population includes individuals aged 60 years or younger at the time of diagnosis, with evidence of vasculitis on imaging. The primary components of the ACR/EULAR classification criteria for Takayasu arteritis include both entry and clinical criteria. Entry criteria encompass age at diagnosis and evidence of vasculitis on imaging. Clinical criteria include factors such as gender, presence of angina or ischemic cardiac pain, arm or leg claudication, vascular bruit, reduced pulse in the upper extremity, carotid artery abnormality, and systolic blood pressure difference in arms. The criteria also consider the number of affected arterial territories and additional imaging criteria, such as symmetric involvement of paired arteries and abdominal aorta involvement with renal or mesenteric involvement. These components are integral to the classification of the disease and help clinicians to accurately diagnose and manage patients with Takayasu arteritis.
